Sorting on apex:pageblocktable columns

Hi,

Is there a way to make the columns in this visualforce page sortable?  It's simply a page that displays the open tasks owned by the current user.

controller:
  
public class tasksController{
    
    List<Task> tk; 
      // toggles the sorting of query from asc<-->desc


    public tasksController(ApexPages.StandardController Controller){
     }  
     
    public List<Task> getResults(){     
        return tk;
    }         
    public PageReference gettk(){
        String userId=UserInfo.getUserId();
        UserId=userId.Substring(0,15);
        tk=[Select Status, Subject, Priority, OwnerId, Owner.Name, WhatId, Response_Needed__c,What.Name, WhoId, Who.Name, ActivityDate from Task WHERE 
             Status != 'Completed' AND (ActivityDate = THIS_WEEK ) AND OwnerId =: UserId ORDER BY ActivityDate DESC LIMIT 25  ];
        return Null; 
    }
}



visualforce page:
  
<apex:page standardController="Task" extensions="tasksController" action="{!gettk}">
<apex:form >
    <html>
    &nbsp;&nbsp;<img src="/img/icon/home32.png"/>
    <font size="5">&nbsp;&nbsp;My Open Tasks Due This Week</font><br></br>

<apex:pageblock >


                    <apex:pageBlockTable value="{!results}" var="tsk">

Deleting a Picklist Value

Hi -

I'm cleaning up some data and I need to delete a Picklist value.  But I get the message:

The picklist value you attempted to delete is the last value for the following record types. This picklist must contain at least one value. Either add another value to the picklist or to the following record type.

 

How do I fix this?


thank you -

Creating a Visualforce Popup window that operates similar to the Lookup popup windows

I'm starting to do some research into what it would take to create a Visualforce popup window similar to the standard salesforce lookup windows.  For now, my intention is to try to come up with a stronger lookup window for one of our custom objects, and at the moment I plant to create a link on a visualforce page to bring the popup up.  (This link will be right next to the existing standard salesforce lookup icon.)
 
I figured I'd start by seeing if anyone else has had any success doing something like this.  The items I am going to tackle first are:
 
1.  Create the popup window.  -  Don't expect this to be a problem.
2.  Pass parameters to the popup through the URL - Don't expect this to be a problem.
3.  Emulate the existing functionality of an existing Salesforce lookup, so that the lookup window will disappear automatically if the parent window is reselected - Not sure how to implement this one yet
4.  Pass a value, in this case, an Id back to the parent window - Not sure how I'm going to do this, but I'm going to attempt to pass some sort of callback function into the popup so it can return a value
 
Being able to do something like this leads to the need to be able to override standard Salesforce lookup functionality.  That way this could be easily implemented on standard pages, in addition to VisualForce pages.
 
If anyone has attempted something like this with Visualforce yet, any learnings would be great!
 
Thanks!
